I have committed a package pkgsrc/net/6to4 that contains a script to set
up 6to4 IPv6. If you always wanted to play with IPv6 but didn't know where
to start, here is it:

 * Make sure your kernel has options INET6 and at least one stf
 * cd /usr/pkgsrc/net/6to4 && make install
 * cd /usr/pkg/etc && cp 6to4.conf-example 6to4.conf
 * Adjust out_if to your outgoing interface. For a modem setup, "ppp0" is
   fine. If you get IPv4 connectivity via LAN, use your ethernet card's
   interface name (le0, ...)
 * 6to4 -v start
 * ping6

The manpage has a bit more details, and a link with an intro to 6to4 at
the end. Enjoy!
